Yeah Haze Shenron is the weakest Shadow Dragon for sure but he did took several hits from Pan and Pan is pretty strong herself. Haze Shenron needs to be delt with quickly because the longer the fight drags on the weaker his opponent gets. Goku was so weak that when he turned SSJ he instantly turned back to normal and was so weak that Haze Shenron was able to blast him and Pan against the wall and GT Goku even at base is no joke.

Characters like Haze Shenron is why GT isn't taken so seriously sometimes. He's weak and only powerscaling makes him strong. But he challenged base Goku. I suppose by reason of that alone he should beat Minato but it's iffy.

Minato trolls him. Also if Goku didn't hold back he could have one shotted him. Same with Pan too since she should be at least small planet level.

'Should be', but isn't.

Baby couldn't blow up the earth with one blast in his strongest form and SSJ4 Goku was impressed when Omega nuked a city. From what we've seen, there's no way in hell that Pan could be a planet buster.
